双（脒）配体作为两个AuMes片段的分子锁起作用。得到的复合物保留了一个灵活的双大环与两个非常规的N-H Cipso氢键和不同的分子内分散力。而不是通过在溶液中的键断裂的双环结构的展开，观察到的构象环反转。
A bis(amidine) ligand operates as a molecular lock for two AuMes fragments. The resulting complex retains a flexible double macrocycle with two non-conventional N–H⋯Cipso hydrogen bonds and distinct intramolecular dispersion forces. Instead of unfolding of the double-ring structure through bond rupture in solution, a conformational ring inversion is observed.
